低氯根稀土氧化物生产工艺改进研究

Study on Improvement of Production Process for Low Chlorine Root Rare Earth Oxide

为了生产出低氯根稀土氧化物,通过对料液与沉淀剂中的有机溶剂夹带物的处理、碳酸稀土洗涤方式及碳酸稀土后处理方式的改进,能有效地控制稀土产品中氯根及其他杂质的含量,得到低氯根的稀土氧化物产品。

In order to produce low chlorine root rare earth oxide,through the treatment of organic solvent entrainment in feed liquid and precipitant,the improvement of rare earth carbonate washing method and process method after rare earth carbonate,the content of chlorine root and other impurities in rare earth products can be effectively controlled,and the low chlorine root rare earth oxide products can be obtained.
